(Phys.org) —Recent progress in the engineering of plasmonic structures has enabled new kinds of nanometer-scale optoelectronic devices as well as high-resolution optical sensing. But until now, there has ...

A new approach that allows objects to become "invisible" has now been applied to an entirely different area: letting particles "hide" from passing electrons, which could lead to more efficient thermoelectric ...

Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner ...

(PhysOrg.com) -- Theorists have long wondered how massive stars--up to 120 times the mass of the Sun--can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns ...

A good tool is both robust and accurate; it doesn't break down easily, or give faulty readings or results. This standard applies to everything from a bathroom scale, or vending machine to a sniper rifle. ...

As computer manufacturers cram ever more processing power onto tiny chips, they face a growing problem. The connections between electronic components that measure just a few billionths of a meter across allow ...

(Phys.org)—Researchers from the NIST Center for Nanoscale Science and Technology and Caltech have developed a new design platform for measuring and exploiting strong interactions between light confined ...

(Phys.org)—Researchers from the NIST Center for Nanoscale Science and Technology have demonstrated a low-noise device for changing the wavelength of light using nanofabricated waveguides created on a silicon-based ...
